> putting it in a mouse would NOT be zoonotic

It sounds like the claim is that it’s “from humanized (ACE2-transgenic) mice“. I assume “humanized” is referring to the genome or something else about the genetics but these organisms still shouldn’t be considered humans (or at least this opinion seems reasonable; if it’s factually wrong I’m open to being corrected).

But if it’s “from” non-human “to” human, isn’t that a zoonotic jump, or is there some mistake in this understanding?
